In psychological science, replicability-repeating a study with a new sample achieving consistent results (Parsons et al., 2022)-is critical for affirming the validity of scientific findings. Despite its importance, replication efforts are few and far between in psychological science with many attempts failing to corroborate past findings. This scarcity, compounded by the difficulty in accessing replication data, jeopardizes the efficient allocation of research resources and impedes scientific advancement. Addressing this crucial gap, we present the (https://forrt-replications.shinyapps.io/fred_explorer), a novel platform hosting 1,239 original findings paired with replication findings. The infrastructure of this database allows researchers to submit, access, and engage with replication findings. The database makes replications visible, easily findable via a graphical user interface, and tracks replication rates across various factors, such as publication year or journal. This will facilitate future efforts to evaluate the robustness of psychological research.

With the persistence of difficult employment, a large number of college students feel anxious and nervous about job hunting. College students with different family economic status have various feelings and performances when faced with employment, possibly due to subjective social class differences. The present study investigated the employment confidence of 611 undergraduates in Chongqing, aimed to ascertain the overall employment confidence of Chinese college students, and tried to analyze how subjective social class works on the employment confidence of college students and its influencing mechanism.

Background: Myocardial infarctions (MI) significantly contribute to the global disease burden and are often followed by psychological conditions such as depression, anxiety, and posttraumatic stress disorder (PTSD). These are frequently underrecognized and insufficiently addressed in clinical care. This study aims to investigate the psychosocial impact of MI, identify risk factors for psychological burden following an MI, and gain insight into the perceived psychological care during hospitalization.

Dysregulated dopaminergic signaling has been implicated in the pathophysiology of major depressive disorder (MDD) and childhood sexual abuse (CSA), but inconsistencies abound. In a multimodal PET-functional MRI study, harnessing the highly selective tracer [C]altropane, we investigated dopamine transporter availability (DAT) and resting-state functional connectivity (rsFC) within reward-related regions among 112 unmedicated individuals (MDD: n = 37, MDD/CSA: n = 18; CSA no MDD: n = 14; controls: n = 43). Striatal DAT and seed-based rsFC were assessed in the dorsal and ventral striatum and the ventral tegmental area.

Gut-derived metabolites are essential for liver fibrogenesis. The aim of this study was to determine the alteration of indole-3-propionic acid (IPA), a crucial tryptophan metabolite, in liver fibrosis and delineate the roles of enterogenic IPA in fibrogenesis. In the present study, metabolomics assays focused on tryptophan metabolism were applied to explore the decreased levels of IPA in the feces and serum of cirrhotic patients, as well as in the feces and portal vein serum of fibrotic mice.

The transition from traditional animal-based approaches and assessments to New Approach Methodologies (NAMs) marks a scientific revolution in regulatory toxicology, with the potential of enhancing human and environmental protection. However, implementing the effective use of NAMs in regulatory toxicology has proven to be challenging, and so far, efforts to facilitate this change frequently focus on singular technical, psychological or economic inhibitors. This article takes a system-thinking approach to these challenges, a holistic framework for describing interactive relationships between the components of a system of interest.
